Toss the broccoli, cauliflower, onion, red pepper, and garbanzo beans with olive oil, salt, and pepper. Be sure to fully coat the vegetables in oil. Spread in a single even layer on a large baking sheet. Bake 15 to 20 minutes, just until vegetables begin to char.
In a small saucepan, bring vinegar and honey to a boil stirring frequently. Reduce to a simmer, continue to cook until the vinegar has reduced by half or about 1/2 cup. Remove from heat and cool.
Place quinoa in the bottom of 4 serving bowls, about 1/2 cup per bowl. On top of the quinoa, place the roasted vegetables, only taking about half of the space in the bowl. About 1 cup of vegetables per bowl. Place the spinach on top of the quinoa, taking up the remaining half. Top the entire bowl with the diced avocado, about 1/3 cup per bowl. Sprinkle with parsley and almonds. Drizzle about 2 tablespoons of the balsamic vinegar and honey mixture on top. Serve and enjoy!
